COMBINATION TOOL.

Specification of Letters Patent. Patent d J 27, 1922 Application filedApril 10, 1920. Serial No. 372,744.

To all whom it may concern:

Be it known that I, ALBERT J. HART, a citizen of the United States, andresident of Cromwell, in the county of Noble and State of Indiana, haveinvented a new and Improved Combination Tool, of which the following isa full, clear, and exact descr1ption.

This invention relates to tools and more particularly to a combinationtool.

Many combination tools have been constructed and designed in order toprovide a" O Y mg alined transverse openings 19 for the resingle toolfor various purposes to take place of a multiplicity; but it has beenfound that in the majority of cases, it is necessary to remove a part ofthe tool in order to adapt the same for various uses, which has beenfound objectionable.

One of the principal objects of the present invention is to provide asimple, compact, and durable tool which is designed to perform the workof aplurality of independent tools without the necessity of removing asingle element of the combinatlon.

Another object of the invention is to provide a tool which is capable offunctioning as a wrench, pliers, a hammer, a nail-puller, a vise, a wirecutter, a clamp, or a nutcracker.

With these and other objects and advantages in view, some of which willbe more readily apparent hereafter, reference is made to the followingdescription, claims,

and accompanying drawings in which- Fi ure 1 is a side elevation view ofthe tool illustrating in. full and dotted lines several positions of theparts thereof;

Fig. 2 is a vertical sectional view therethrough;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1; and

Fig. 4 is a-fragmentary side view of the tool illustrating one of theuses of the same.

1 1, the outer side face'of the former constituting a hammer head andthe inner underside of the latter a fixed jaw having teeth 15 formedthereon. The outer end of the head 12 is formed to provide a curved camsurface 16 which merges respectively at its opposite ends into thehammer head and the outer extremity of the fixed jaw, and a portion ofthe under edge of the laterally projecting portion constitutingthehammer head 131s sharpened as at 17. A traveler 18 in the nature ofarectangular sleeve havception of a nut 20, is slidable on the threadedportion of the shank, movements of the same being efi'ected by means ofthe engagement of the threaded bore of the nut with the worm threads 11.A transverse pin 21 passed through the outer threaded extremity of theshank 10 serves to limit the outward movement of the traveler andprevent its enthe removal from the shank. A slidable member movable onthe shank between the traveler 18 and the head 12 is provided andincludes the longitudinal bars 22 and 23 disposed at the opposite sideedges of the shank 10 and connectedby the side plates 24 by means ofrivets 25. The upper extremityof --the bar 22 is enlarged to provide amovable is extended above the .side' plates 24 and is sharpened as at 28whereby to co-act with the sharpened edge 17 to constitute a wirecutter. The lower extremity of each bar 22 and 23 is extended below thelower end of the side plates 24 and is apertured for thesubstantially atoggle connection between The the traveler and the movable member.extremity of each link adjacent its pivot 33 is provided with anoutwardly disposed lug 34. The outerfree extremity 35 of each 1ever arm30 constitutes a handle which is preferably of semicircular formation incross-sect1onto provide a rounded gripping surface for the hand, andsaid'handles also serve, when closed, as a partial housing to preventthe contact of the operators hand with the nut 20. v

In use of the device it will be understood that upon turning the nut 20the traveler 18 will be advanced'toward or awayv from the head 12, saidnut serving also as a; means for retainin positions. he levers may thenbe employed as a means for effecting relative adjustments of the movablemember with respect tothe head 12- and the traveler 18. whereby toadvance the movable jaw 26 to-' ward or away from the fixed jaw 14. In"

use of the device as an ordinary wrench the levers 30 are closedasuillustrated in full lines in Fig. l of the drawing, and the nut 20 isused in the usual manner to advance the movable jaw 26 toward the fixedjaw 14. In this instance the movable member, the traveler, and the.toggle connection merely function as a single travelermem'ber. In use ofthedevice as a wire cutt'erthe traveler 18, with the levers 30 in closedposition, is advanced together with the movable'member toward the head12 until the edges 17 and 28 contact; the levers are then opened and thewire to be cutinserted between the edges 17 and 28 and the levers arethen brought together to advance the edges 17. and 28 toward each otherfor severing the wire. In use of the device as a pipe wrench the jaws 11 and 26 are adjuste apart to provide a space slightly less than thediameter of the plpe and the handles are opened to permit of theinsertion of the pipe therebetween; the handles are then closed untilthe jaws grip the ipe and then loosened to permit retrod; movement ofthe wrench and allow the gm j awsto obtain a new grip. In use of thedevice as a clamp the movable jaw is advanced toward the fixedjaw togrip the object with the levers 30 slightly opened; the levers 30 arethen moved toward each other until the inner sides of the same contactwith the lugs 34. This operation will dispose the pivots 32 inside of adead-center line extending between the pivots 29 and 33, thereb lockingthe jaws in clamping relation witi respect to the object. In use-of thedevice as a nailpuller as illustrated in Fig. 4 the teeth of the jaws 14and 26 are designed to engage the head of the nail adjacent their outerextremities under the action of the compression of the handles 35, andusing the curved sur-' face 16 as a fulcrum the handle of the wrench isused as a lever to extract the'nail, In use of the device as a hammer,it is obvious that the handles 35 are gripped in closed position and thestriking surface.

As illustrated in Fig. 1 the rearwardly ex.-

tended terminal portions of the bars 22 and 23 are directly connected tothe handles by I the traveler in its adjusted.

head 13 used as the meansofrivets 29 so that pressure on the handles istransmitted directly through the bars to'the work-engaging devices. Thisgreatly lessens the strain on the various partsof the device and is afeature not shown in the art.-

While there has been illustrated and described asingle and-preferredembodiment of the invention, no limitation is made to the precisedetails of construction, and it is understood that variations andmodifications which fall within the scope of the appended claims may beresorted to when found ex pedient. L

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1.-A tool comprisinga shank having a fixed jaw, a second jaw slidable on said shank andhaving rearwardly projecting extensions at opposite edges of said shank,levers arranged on opposite edges of said shank and pivoted to theextensions of said sliding jaw, a traveler on said shank and havingears, and links pivoted to said ears and said levers, said levers beingformed with channels receiving said links and ears, whereby the hand ofthe operator is protected from engagement with the links and ears.

2. The construction set forth in claim 1,

and a, nut associated with the traveler and threaded on said shank.

'3. A tool comprising a shank having a fixed head, a member slidable onsaid shank and consisting of oppositely arranged side plates andseparately formed bars arranged at the edges of the shank between theside plates, means passing through the side plates and the bars forconnecting the same, the

forward ortions of said bars being extended beyond work-engaging meanscooperating with said head and an adjusting device for said slidingmember;

4. A tool comprisin' a shank having a fixed head, a member s idable onsaid shank and comprising oppositely arranged'side said side plates andformed with.

plates and separately formed bars arranged at the edges of the shankbetween the side plates, means passing throughtheiside plates and thebars for connecting the same, the forward ortions of said bars beingextended beyond said Side plates and formed with work-engaging meanscooperating with said ,head, the rear portions of said bars terminatingrearwardly of said side plates, and

means connected directly to the extended rear terminal portions of saidbars for positioning (said member.
